Systems of networking power management systems are disclosed, wherein the systems receive control parameters from a control terminal and bring about demand response, curtailment, and other load management actions. One control terminal may be used to control many zones in different ways, and the load management actions may be automated to improve efficiency and predictability of the results of demand response actions. Some of the systems may be mobile and connectable to different sites in the network to respond to changing needs in the utility distribution grid. Large demand response requirements may be distributed among multiple sites or systems in order to encourage and enable participation in demand response programs by customers that would not traditionally be able to do so because of not being able to produce sufficient demand response results individually.
